Himitsu Bako MINI 3 | 7 Step Japanese XS Puzzlebox

Himitsu Bako Mini 3

The newest addition to the beloved MINI Series.

In the quiet workshops where patience becomes tradition, a true Himitsu Bako is never judged by its size.

At only 45 × 45 × 30 mm and requiring just 40 grams of filament, the Himitsu Bako Mini 3 carries the soul of its full-sized ancestors. Hidden within this tiny masterpiece lies a surprisingly spacious compartment, protected by 7 carefully concealed moves that reward observation, precision, and calm hands.

But this edition introduces something entirely new. Familiar techniques alone will not reveal its secret. New styles of movement have been woven into its mechanism, offering even experienced puzzle enthusiasts a fresh challenge.

Small enough to fit in your pocket. Clever enough to keep you guessing.

A true craftsman's puzzle, reimagined for the modern maker.

Attention:
This model contains moving parts and relies on tight tolerances. It is strongly recommended to print using a relatively new or well-maintained nozzle. Worn or heavily used nozzles may result in inaccurate prints, which can cause parts to fuse together or fail to meet the required tolerances. This may prevent components from moving correctly or cause them to become stuck.
